NI404 is an Open Source DIY Hardware Sampler + Sequencer
The NI404 is an open-source sampler and sequencer, based on the Teensy Microcontroller and Audioboard from PJRC, that’s designed to offer an accessible entry point into the world of music creation.
Features:
- Easy to Use – The NI404 lets users create complex sound patterns without any prior knowledge of musical instruments or equipment. It’s perfect for beginners and makers alike.
- Dynamic Control – At the heart of the NI404 is a 16×16 RGB LED panel display, paired with three rotary-push encoders. Navigate a cursor across the grid, where each row signifies a voice and each column a potential note, allowing for up to 16 pitches per note. This feature enables the mixing of up to 8 voices simultaneously.
- Real-Time Interaction. – Adjust samples, instruments, pitches, notes, volume, BPM, velocity, and effects in real-time without pausing.
- Etch-A-Sketch style note drawing
- On-the-fly note deletion and sample muting
- Adjustable volume, BPM (40 – 200), pattern, and note velocity
- Up to 30-second sample length with seamless looping
- Use your own samples on the SD-Card – in a simple file structure
- Load up to 8 voices / samples (Wav format) plus an additional onboard synth voice
- 16-bar patterns across 8 pages, totaling 128 bars per song
- Save and load up to 100 patterns / songs on the SD card
- Autosave and autoload functions
- Access and manage samples while playing, with support for up to 999 samples on the SD card and the ability to predefine multiple voices as a SampleSet.
- Fully Independent – Operates without a computer, generating all sounds on the device itself.
- USB powered (5V) and Arduino code is published under the MIT License.
